In 1917 Thomas Parnell published the first piece of Physics research from UQ in the Proceedings of the Physical Society, London  under the title ‘An Alternating Current Bridge Method of Comparing Two fixed Inductances at Commercial Frequencies.’

The detector he used survives today. Sumpner’s relecting electrodynamometer, constructed by Robert Paul, is a classic late nineteenth century electrical instrument.

This talk will uncover its inventor, its maker and his two careers, and how Parnell used it.
